Technical Field

[0001] This application relates to the field of battery manufacturing equipment technology, specifically a transfer device and sorting equipment. Background Technology

[0002] With the booming development of the electric vehicle, smartphone, and other electronic product markets, batteries, as one of their core energy components, have seen their production efficiency and capacity become a key focus of the industry. During battery production, cells need to be sorted based on factors such as cell capacity, cell voltage, or cell internal resistance.

[0003] In the battery cell sorting process, a transfer device is needed to transport the cells from upstream to downstream. In existing technology, the transfer device moves to the upstream station, where an upstream robot transfers the cells onto the transfer device; then the transfer device moves to the downstream station, where a downstream robot transports the cells from the transfer device to different sorting positions, thus achieving cell sorting. To improve cell sorting efficiency, the number of transfer devices and robots needs to be increased. However, increasing the number of transfer devices and robots results in a larger space requirement for the sorting equipment, making it unsuitable for space-constrained situations.

[0016] In some embodiments, the first drive assembly further includes a first drive shaft rotatably connected to the mounting bracket, and the drive end of the first rotary drive member is connected to the first drive shaft.

The first drive pulleys of the two first belt drive mechanisms are all mounted on the first drive shaft. The first bearing assembly is fixedly connected to the first drive belts of the two first belt drive mechanisms.

[0018] In some embodiments, the first drive assembly further includes a second belt drive mechanism, which includes a second driven pulley, a second driving pulley, and a second drive belt. The second driven pulley is mounted on the first drive shaft, and the second driving pulley is mounted on the output shaft of the first rotary drive member and spaced apart from the second driven pulley.

When the second supporting component moves below the unloading station, the lifting component first raises it to the unloading station, the downstream robot arm removes the battery cells from the second supporting component, and then the lifting component lowers it to its original position. To avoid interference with each other, the first and second load-bearing components alternately arrive at the loading and unloading stations. That is, when the first load-bearing component arrives at the loading station, the second load-bearing component arrives at the unloading station, and when the first load-bearing component arrives at the unloading station, the second load-bearing component arrives at the loading station.

[0026] In this way, by using the first and second carrier components to alternately transfer battery cells between the loading and unloading stations, the transfer efficiency of the battery cells is greatly increased, thereby increasing the sorting efficiency. Furthermore, by placing the second carrier component below the first carrier component and using a lifting mechanism to load at the loading station and unload at the unloading station, the space below the first carrier component is fully utilized, resulting in a compact structure with high space utilization. This avoids increasing the space required for the equipment and better meets the needs of space-constrained environments. Attached Figure Description

[0036] Please see Figures 1 to 3 This application provides a transfer device for receiving battery cells transferred by an upstream robot at a loading station a1 and conveying the received battery cells to a unloading station a2. A downstream robot grabs the battery cells conveyed to the unloading station a2 and transfers the grabbed battery cells to different positions according to the battery cell capacity, battery cell voltage, or battery cell internal resistance, thereby realizing the sorting of battery cells.

[0037] The transfer device includes a mounting frame 10, a first support component 20, a second support component 30, and a lifting component 40. The first support component 20 is movably connected to the mounting frame 10 along a first direction X1 and is movable relative to the mounting frame 10 between a loading station a1 and a unloading station a2. The second support component 30 is also movably connected to the mounting frame 10 along the first direction X1 and is located below the first support component 20. The second support component 30 is movable relative to the mounting frame 10 between below the loading station a1 and below the unloading station a2. The lifting component 40 is mounted on the mounting frame 10 and is used to drive the second support component 30, which is moved below the loading station a1 or the unloading station a2, to rise to either the loading station a1 or the unloading station a2.

[0038] In actual use, the aforementioned transfer device allows the first supporting component 20 to move between the loading station a1 and the unloading station a2. When the first supporting component 20 moves to the loading station a1, it receives the battery cells transported by the upstream robot arm. When the second supporting component 30 moves to the unloading station a2, the downstream robot arm removes the battery cells from the first supporting component 20. Simultaneously, the second supporting component 30 moves between below the loading station a1 and below the unloading station a2. When the second supporting component 30 moves below the loading station a1, the lifting component 40 first raises the second supporting component 30 to the loading station a1 to receive the battery cells transported by the upstream robot arm. The lifting component 40 then lowers the second supporting component 30 to its original position. When the second support component 30 moves below the unloading station a2, the lifting component 40 first lifts the second support component 30 to the unloading station a2. The downstream robot removes the battery cells from the second support component 30, and then the lifting component 40 lowers the second support component 30 to its original position. To avoid interference, the first support component 20 and the second support component 30 alternately reach the loading station a1 and the unloading station a2. That is, when the first support component 20 reaches the loading station a1, the second support component 30 reaches the unloading station a2, and when the first support component 20 reaches the unloading station a2, the second support component 30 reaches the loading station a1.

[0039] In this way, by using the first carrier component 20 and the second carrier component 30 to alternately transfer battery cells between the loading station a1 and the unloading station a2, the transfer efficiency of the battery cells is greatly increased, thereby increasing the sorting efficiency of the battery cells. Furthermore, by placing the second carrier component 30 below the first carrier component 20 and using a lifting mechanism to load at the loading station a1 and unload at the unloading station a2, the space below the first carrier component 20 is fully utilized. This results in a compact structure with high space utilization, avoiding the need to increase the space occupied by the equipment and better meeting the requirements of space-constrained environments.

[0040] In embodiments of this application, the lifting assembly 40 includes a first lifting mechanism 41 and a second lifting mechanism 43. The first lifting mechanism 41 is arranged below the loading station a1, and when the second supporting assembly 30 moves below the loading station a1, the second supporting assembly 30 is located between the loading station a1 and the first lifting mechanism 41. The first lifting mechanism 41 drives the second supporting assembly 30 located below the loading station a1 to rise and fall, so that the second supporting assembly 30 rises to the loading station a1 to receive the battery cell, and then falls. The second lifting mechanism 43 is arranged below the unloading station a2, and when the second supporting assembly 30 moves below the unloading station a2, the second supporting assembly 30 is located between the unloading station a2 and the second lifting mechanism 43. The second lifting mechanism 43 drives the second supporting assembly 30 located below the unloading station a2 to rise and fall, so that the second supporting assembly 30 rises to the unloading station a2 for unloading, and then falls.

[0041] Specifically, in this embodiment, the first lifting mechanism 41 includes a first lifting drive 411, a first lifting seat 412, and a first push rod 413. The first lifting drive 411 is mounted on the mounting bracket 10, and the first lifting seat 412 is mounted on the driving end of the first lifting drive 411, enabling the first lifting drive 411 to drive the first lifting seat 412 to rise or fall. One end of the first push rod 413 is connected to the first lifting seat 412, and the other end of the first push rod 413 extends upward. When the first lifting drive 411 drives the first lifting seat 412 to rise, it can drive the first push rod 413 to lift the second bearing assembly 30 upward until the second bearing assembly 30 reaches the loading station a1; when the first lifting drive 411 drives the first lifting seat 412 to fall, the second bearing assembly 30, which has been lifted to the loading station a1, falls together with the first push rod 413. Optionally, the first lifting drive 411 can be a cylinder.

[0042] Furthermore, there can be multiple first push rods 413, and multiple first push rods 413 can be used to lift the second bearing component 30 simultaneously, making the lifting and lowering movement of the second bearing component 30 more stable.

[0043] Furthermore, the first lifting mechanism 41 also includes a first guide seat (not shown) mounted on the mounting bracket 10, which has a first guide hole through which the first push rod 413 passes. In this way, the lifting movement of the first push rod 413 is guided by the first guide hole.

[0044] Specifically, in this embodiment, the second lifting mechanism 43 includes a second lifting drive 431, a second lifting seat 432, and a second push rod 433. The second lifting drive 431 is mounted on the mounting bracket 10, and the second lifting seat 432 is mounted on the driving end of the second lifting drive 431, enabling the second lifting drive 431 to drive the second lifting seat 432 to rise or fall. One end of the second push rod 433 is connected to the second lifting seat 432, and the other end of the second push rod 433 extends upward. When the second lifting drive 431 drives the second lifting seat 432 to rise, it can drive the second push rod 433 to lift the second bearing assembly 30 upward until the second bearing assembly 30 reaches the unloading station a2; when the second lifting drive 431 drives the second lifting seat 432 to fall, the second bearing assembly 30, which has been lifted to the unloading station a2, falls together with the second push rod 433. Optionally, the second lifting drive 431 can be a cylinder.

[0045] Furthermore, there can be multiple second push rods 433, which can be used simultaneously to lift the second bearing assembly 30, making the lifting and lowering movement of the second bearing assembly 30 more stable.

[0046] Furthermore, the second lifting mechanism 43 also includes a second guide seat 434 mounted on the mounting bracket 10, which has a second guide hole through which the second push rod 433 passes. Thus, the lifting movement of the second push rod 433 is guided by the second guide hole.

[0047] In embodiments of this application, the transfer device further includes a first drive assembly, which includes a first belt drive mechanism 51 and a first rotary drive member 52. The first belt drive mechanism 51 includes a first driving pulley 511, a first driven pulley 513, and a first transmission belt 515. The first driving pulley 511 and the first driven pulley 513 are rotatably connected to the mounting frame 10 and are spaced apart from each other along a first direction X1. The first transmission belt 515 is tensioned and sleeved between the first driving pulley 511 and the first driven pulley 513, so that when the first driving pulley 511 rotates, it can drive the first transmission belt 515 to move forward sequentially along the first direction X1. The first bearing assembly 20 is drively connected to the first transmission belt 515, so that the first transmission belt 515 can drive the first bearing assembly 20 to move relative to the mounting frame 10 along the first direction X1. The first rotary drive component 52 is mounted on the mounting bracket 10, and its drive end is connected to the first drive pulley 511, enabling the first rotary drive component 52 to drive the first drive pulley 511 to rotate. Thus, when the first load-bearing assembly 20 needs to move along the first direction X1, the first rotary drive component 52 drives the first drive pulley 511 to rotate. The first drive pulley 511 then drives the first transmission belt 515 to reciprocate between the first drive pulley 511 and the first driven pulley 513, thereby causing the first transmission belt 515 to drive the first load-bearing assembly 20 to reciprocate along the first direction X1. Optionally, the first rotary drive component 52 can be a motor.

[0048] Specifically, in this embodiment, the first mounting bracket 10 is provided with two first slide rails (not shown in the figure). Both first slide rails extend longitudinally along a first direction X1 and are spaced apart along a second direction X2 perpendicular to the first direction X1. The first support component 20 is supported on these two first slide rails and is movable along them. Thus, the two first slide rails simultaneously support the first support component 20 and simultaneously guide its movement along the first direction X1.

[0049] In a specific embodiment, the first drive assembly further includes a first drive shaft 53, which is rotatably connected to the mounting bracket 10. The drive end of the first rotary drive member 52 is connected to the first drive shaft 53, enabling the first rotary drive member 52 to drive the first drive shaft 53 to rotate relative to the mounting bracket 10. Two first belt drive mechanisms 51 are provided, which are respectively arranged on opposite sides of the first bearing assembly 20 in the second direction X2. The first drive pulleys 511 of the two first belt drive mechanisms 51 are both mounted on the first drive shaft 53, so that when the first drive shaft 53 rotates, it can drive the first drive pulleys 511 of the two first belt drive mechanisms 51 to rotate synchronously. Thus, the first drive shaft 53 is driven to rotate by the first rotary drive component 52, and the first drive shaft 53 drives the first drive pulleys 511 of the two first belt drive mechanisms 51 to rotate synchronously. The first drive pulleys 511 of the two first belt drive mechanisms 51 then drive the first drive belts 515 of the two first belt drive mechanisms 51 to move synchronously along the first direction X1. In turn, the first drive belts 515 of the two first belt drive mechanisms 51 drive the second bearing component 30 to move along the first direction X1, thereby realizing the movement of the first bearing component 20 along the first direction X1 between the loading station a1 and the unloading station a2.

[0050] Furthermore, the first drive assembly also includes a second belt drive mechanism 54, which includes a second driven pulley 542, a second driving pulley 541, and a second drive belt 543. The second driven pulley 542 is also mounted on the first drive shaft 53, so that the second driven pulley 542 can rotate together with the first drive shaft 53. The second driving pulley 541 is mounted on the output shaft of the first rotary drive member 52, so that the first rotary drive member 52 can drive the second driving pulley 541 to rotate. The second driving pulley 541 and the second driven pulley 542 are spaced apart along a predetermined direction. The second drive belt 543 is tensioned and sleeved between the second driving pulley 541 and the second driven pulley 542, so that the second driving pulley 541 can drive the second driven pulley 542 to rotate through the second drive belt 543, and the second driven pulley 542 then drives the first drive shaft 53 to rotate.

[0051] It should be noted that the second belt drive mechanism 54 is not necessary. In other embodiments, the output shaft of the first rotary drive member 52 can also be connected to the first drive shaft 53 through other transmission components. For example, the output shaft of the first rotary drive member 52 can be connected to the first drive shaft 53 through a coupling. As long as the first rotary drive member 52 can drive the first drive shaft 53 to rotate, it is not limited here.

[0052] In embodiments of this application, the transfer device further includes a base support 60, which is movably connected to the mounting frame 10 along a first direction X1 and located below the first support component 20. The base support 60 supports the second support component 30 and drives the second support component 30 to move along the first direction X1, allowing the second support component 30 to reciprocate between below the loading station a1 and above the unloading station a2.

[0053] Thus, when the base support 60 moves the second load-bearing component 30 on it to below the loading station a1, the first lifting drive 411 drives the first lifting seat 412 and the first push rod 413 to rise, causing the first push rod 413 to lift the second load-bearing component 30 on the base support 60 until the second load-bearing component 30 is lifted to the loading station a1. After the upstream robot moves the battery cell onto the second load-bearing component 30, the first lifting drive 411 drives the first lifting seat 412 and the first push rod 413 to descend until the second load-bearing component 30 descends onto the base support 60.

[0054] When the base support 60 moves the second load-bearing component 30 on it to below the unloading station a2, the second lifting drive 431 drives the second lifting seat 432 and the second push rod 433 to rise, so that the second push rod 433 lifts the second load-bearing component 30 on the base support 60 until the second load-bearing component 30 is lifted to the unloading station a2. After the downstream robot removes the battery cell from the second load-bearing component 30, the second lifting drive 431 drives the second lifting seat 432 and the second push rod 433 to descend until the second load-bearing component 30 descends onto the base support 60.

[0055] It is understandable that the base support 60 is located in a position that is higher than the first guide seat and the second guide seat 434 in the vertical direction, and lower than the first bearing component 20 in the vertical direction, so that when the base support 60 drives the second bearing component 30 thereon to move along the first direction X1, it will not interfere with the first guide seat, the second guide seat 434 and the second bearing component 30.

[0056] Furthermore, the base 60 has a perforated hole 61 through which each of the first push rods 413 and each of the second push rods 433 pass, thereby enabling each of the first push rods 413 or each of the second push rods 433 to pass through the perforated hole 61 to lift the second support assembly 30 on the base 60.

[0057] Furthermore, a positioning pin 62 is installed on the base 60, and a positioning hole is provided on the second support component 30. The positioning pin 62 can be inserted into the positioning hole in a corresponding manner, thereby positioning the second support component 30. Thus, when the first push rod 413 or the second push rod 433 lifts the second support component 30, the second support component 30 gradually rises, causing the positioning pin 62 to retract from the positioning hole on the second support component 30. When the first push rod 413 or the second push rod 433 descends, the second support component 30 descends until it is supported on the base 60.

[0058] Specifically, in this embodiment, the first mounting bracket 10 is provided with two second slide rails 13, both of which extend longitudinally along a first direction X1 and are spaced apart along a second direction X2. The base support 60 is supported on these two second slide rails 13 and is movable along them. Thus, the two second slide rails 13 support the base support 60 and guide its movement along the first direction X1.

[0059] In embodiments of this application, the transfer device further includes a second drive assembly, which includes a third belt drive mechanism 71 and a second rotary drive member 72. The third belt drive mechanism 71 includes a third driving pulley 711, a third driven pulley, and a third transmission belt 715. The third driving pulley 711 and the third driven pulley are rotatably connected to the mounting frame 10 and are spaced apart from each other along a first direction X1. The third transmission belt 715 is tensioned and sleeved between the third driving pulley 711 and the third driven pulley, so that when the third driving pulley 711 rotates, it can drive the third transmission belt 715 to move between the third driving pulley 711 and the third driven pulley. The base 60 is fixedly connected to the third transmission belt 715, so that the third transmission belt 715 can drive the base 60 to reciprocate along the first direction X1. The second rotary drive component 72 is mounted on the mounting bracket 10, and its drive end is connected to the third drive pulley 711, enabling the second rotary drive component 72 to drive the third drive pulley 711 to rotate. Thus, when the base support 60 needs to move along the first direction X1, the second rotary drive component 72 drives the third drive pulley 711 to rotate. The third drive pulley 711 drives the third transmission belt 715 to reciprocate between the third drive pulley 711 and the third driven pulley, thereby causing the base support 60 to reciprocate along the first direction X1. Optionally, the second rotary drive component 72 can be a motor.

[0060] In a specific embodiment, the second drive assembly further includes a second drive shaft 73, which is rotatably connected to the mounting bracket 10. The drive end of the second rotary drive member 72 is connected to the second drive shaft 73, enabling the second rotary drive member 72 to drive the second drive shaft 73 to rotate relative to the mounting bracket 10. Two third belt drive mechanisms 71 are provided, which are respectively arranged on opposite sides of the base 60 in the second direction X2. The third drive pulleys 711 of the two third belt drive mechanisms 71 are both mounted on the second drive shaft 73, so that when the second drive shaft 73 rotates, it can drive the third drive pulleys 711 of the two third belt drive mechanisms 71 to rotate synchronously. Thus, the second drive shaft 73 is driven to rotate by the second rotary drive 72, and the second drive shaft 73 drives the third drive pulleys 711 of the two third belt drive mechanisms 71 to rotate synchronously. The third drive pulleys 711 of the two third belt drive mechanisms 71 then drive the third drive belts 715 of the two third belt drive mechanisms 71 to move synchronously along the first direction X1. In turn, the third drive belts 715 of the two third belt drive mechanisms 71 drive the base 60 to reciprocate along the first direction X1, thereby realizing that the base 60 drives the second bearing assembly 30 to reciprocate between the loading station a1 and the unloading station a2.

[0061] Furthermore, the second drive assembly also includes a fourth belt drive mechanism 74, which includes a fourth driven pulley 742, a fourth driving pulley 741, and a fourth drive belt 743. The fourth driven pulley 742 is also mounted on the second drive shaft 73, allowing it to rotate together with the second drive shaft 73. The fourth driving pulley 741 is mounted on the output shaft of the second rotary drive member 72, enabling the second rotary drive member 72 to drive the fourth driving pulley 741 to rotate. The fourth driving pulley 741 and the fourth driven pulley 742 are spaced apart along a predetermined direction. The fourth drive belt 743 is tensioned and sleeved between the fourth driving pulley 741 and the fourth driven pulley 742, allowing the fourth driving pulley 741 to drive the fourth driven pulley 742 to rotate via the fourth drive belt 743, and the fourth driven pulley 742 in turn drives the second drive shaft 73 to rotate.

[0062] It should be noted that the fourth belt drive mechanism 74 is not necessary. In other embodiments, the output shaft of the second rotary drive member 72 can also be connected to the second drive shaft 73 through other transmission components. For example, the output shaft of the second rotary drive member 72 can be connected to the second drive shaft 73 through a coupling. As long as the second rotary drive member 72 can drive the second drive shaft 73 to rotate, it is not limited here.

[0063] Based on the aforementioned transfer device, this application also provides a sorting device. This sorting device includes an upstream robot, a transfer device as described in any of the preceding embodiments, and a unloading robot. The upstream robot is used to transport the battery cells to be sorted onto the first support component 20 or the second support component 30, which has been moved to the loading station a1. The downstream robot is used to transfer the battery cells moved to the unloading station a2 onto the first support component 20 or the second support component 30 to different sorting positions according to the cell capacity, cell voltage, or cell internal resistance of each battery cell, thereby achieving the sorting of the battery cells.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
